change an EFI to carb?

[crazypete]

Ok... here's what you'll need:

mechanical fuel pump + eccentric + timing chain cover : $170?
A carb (duh) I like the holley street performers: $350
An intake: $150
85 mustang distributor with vacuum advance: $50
steel gear for dist + installation onto dist: $50
Good ignition box (MSD AL6): $300? (your computer cannot control spark anymore)
aircleaner assembly: $100?
You can fasion a throttle cable bracket from the efi throttle cable bracket by sawing off the end and leaving a notch, pounding it 90 degrees , drilling a hole and using this notch as the mounting plate.

You'll need to do some wiring to get the dashboard guages working, but it's not a huge deal. Just flip over the guage cluster and the printed plastic is labelled. Trace to the harness , splice the temp sensor wire to the temp guage wire for instance.

It's so much more fun to have a carb and the milage isnt that bad at all. I have never had the car fail to start since and the worst that has happened is a little sputtering when not set right. No more "engine dies mysteriously" scenarios.

Oh yeah, have fun stripping down the enginebay. I reccomend you do this: Airpump outlet tube directly to the crossovertube behind the heads (Doesnt really backfire if the carb is set properly). You dont have a computer to control the tab/tad solenoids anymore. Rip that wiring and tubing out. Hook the oil filler neck stem to the underside of the air cleaner. now you have pcv. I tried doing EGR, but the car refused to run, so I tossed the system. I reccomend scrapping the vacuum tree since you dont really need it anymore and run a hose over to the brake booster (and tee it at the booster and get a vacuum guage hooked up inside. You'll need it to tune the carb). Dont waste your time with fuel pressure guages since with a mechanical fuel pump, this is rarely an issue.

Have fun
